A rotational coupling device is provided with an integrated rotor and brake disc to simplify design of the device and remove liquids from the device when used in a wet environment. The rotor is configured for rotation about a rotating hub and includes a first member defining one pole of the rotor and a second member defining a second pole of the rotor and a braking surface. The second member is coupled to the first member, but axially movable relative to the first member. During clutch engagement, an electromagnetic circuit used to engage the clutch urges the second member into engagement with the first member for rotation. When the clutch is disengaged, the second member disengages from the first member to create a fluid flow path between the members and engages a brake plate to halt rotation of the rotor.
